The Innovation Center, which is part of Metro's Silver Line extension to Dulles International Airport and beyond, is under construction on July 26, 2017 in Herndon, Va. ( Katherine Frey / The Washington Post). Rachel Weiner Local reporter covering a federal court in Alexandria, Virginia, and a local court in Arlington and Alexandria. Dec. 7 at 1:01 PM An entrepreneur who falsified records to hide the fact that the concrete used in the construction of Metro's Silver Line was defective was sentenced on Friday to pay $ 1.4 million and spend a year in jail, although it is not clear that he will do it. actually serve that time. District Judge T. Ellis III said that Andrew Nolan, 28, cooperates with investigators and may never go to jail. A civil action against the concrete society of his family is in progress. Universal Concrete has manufactured more than 1,500 exterior wall panels in five of the six new stations along the Silver Line Extension to Dulles International Airport and beyond, as part of the project. a $ 6.1 million contract. Nolan admitted that when he was in charge of quality control, he had told employees to report false data on the amount of oxygen in the concrete panels. Actual data showed that there was not enough air in the concrete to prevent damage in cold weather. "They will reject these panels," Nolan told an employee, according to information filed by the court. "We need to change the data." US Attorney Uzo Asonye told the court that the panels should now be treated regularly with a special spray to prevent deterioration, for a total estimated cost of $ 700,000. Nolan agreed to pay double that amount throughout his life in the form of criminal restitution and a civil judgment. Virginia and the federal government are still suing Nolan's uncle, Donald Faust Jr., and the company against the bad concrete. The civil suit alleges that the management of Universal Concrete has been warned repeatedly that Nolan "cooks the books" without doing anything. A vice president who requested an internal audit was fired, according to the civil complaint. "He was overwhelmed," said defense lawyer John Francis Lauro in court. "He was doing his best to assume the responsibility that had been entrusted to him." The company was created by Nolan's grandfather and was run by his uncle at the time. Nolan's first supervisor told him to falsify data, his lawyer said. In June 2016, Nolan left the family business and found another job. "He could not stand it anymore," said Lauro. When calling FBI earlier this year, Lauro said Nolan "told the agents everything" and "tried to fix it." Ellis, the federal judge in Alexandria, suggested that Nolan also participate in the Silver Line investigation. He delayed Nolan's incarceration, telling Asonye: "This period is sort of under your control," and said that a prison appointment was not final. .
